 Solitary nucleus - Wikipedia, the free encyclopedia
The solitary nucleus and tract are structures in the brainstem that carry and receive visceral sensation and taste from the facial (VII), glossopharyngeal (IX), vagus (X) cranial nerves, as well as the cranial part of the accessory nerve (XI).
The nucleus is located along the length of the medulla (with a small portion in the lower pons).
From the solitary nucleus, most information goes to the hypothalamus and cingulate gyrus, as well as to other nuclei in the brainstem (such as visceral motor or respiratory centres).

In the pons, the primary sensory axons terminate either in the principal sensory nucleus of V (or chief sensory nucleus) (#6197) or turn caudally to form the descending tract of V (or spinal tract of V) (#4621) (fig 6b).
The spinal or descending nucleus of V is functionally equivalent to the dorsal horn.
Is this tract efferent or afferent to the descending nucleus?

 Cerebellum - Wikipedia, the free encyclopedia
Most of the efferent fibers originate within the dentate nucleus which in turn project to various midbrain structures including the red nucleus, the ventral lateral/ventral anterior nucleus of the thalamus, and the medulla.
The dentatorubrothalamocortical (dentate nucleus > red nucleus > thalamus > premotor cortex) and cerebellothalamocortical (cerebellum > thalamus > premotor cortex) pathways are two major pathways that pass through this peduncle and are important in motor planning.
In the cerebellum, the PICA supplies blood to the posterior inferior portion of the cerebellum, the inferior cerebellar peduncle, the nucleus ambiguus, the vagus motor nucleus, the spinal trigeminal nucleus, the solitary nucleus, and the vestibulocochlear nuclei.

 Nitric oxide – Its importance in swallowing, inflammatory bowel disease and cirrhotic cardiomyopathy
Nitric oxide synthase (NOS) is localized in the central nervous system, including the nucleus of the solitary tract, nucleus ambiguus and dorsal motor nucleus of the vagus.
In rats and rabbits, NOS has been shown to be present in the nucleus subcentralis of the nucleus of the solitary tract, and is thought to be responsible for the central programming of the striated muscle component of esophageal peristalsis.
The central pattern generated for swallowing and esophageal peristalsis is suggested to be a serial network of linked neurons within the nucleus of the solitary tract and neighbouring reticular formation, and there is likely one subnetwork for the oropharyngeal phase and the other for the esophageal phase of swallowing.
